I had a AC engineer tell me that's the way you want it. A system that is too big will short cycle and it won't run long enough to remove the humidity. When it's hot, my system may run non stop for a few days but the humidity is low. Perfect. 78° and 40% is much more comfortable than 77° and 70%. No need to get it cold but clamy. (like the old stores with the chiller systems do)
